(Galeotti, No. 1145, Vera Cruz, in uliginosis alt. 500 ped.) 
This very distinct species is enumerated among Galeotti’s 
Mexican plants (Enum. Acad. Reg. Brux. tom. xii. Bull. No. 2.) 
under the name of “ Nicotiana plumbaginifolia ? Wild," and is said 
to be found also near Jalisco, in the Province of Guadalaxara, at 
an elevation of from 3,000 to 5,000 feet, and at Juquila, near the 
coast at Oaxaca, on the borders of the Pacific, at the same eleva- 
tion. The specimen consists of a simple, erect, and nearly straight 
stem, with internodes of three quarters of an inch distant; these 
mostly exhibit large cicatrices of the fallen leaves of the previous 
year, and above these arise, generally, a pair of recent leaves, and a 
solitary pendent flower : at the termination of the branch, the axils 
become closer, the leaves and flowers more fasciculated : only a 
single rectangular spine is here seen, which is half an inch in length : 
the leaves are quite spathulate, one inch and three quarters long, 
in addition to the caniculate petiole of half an inch im length, into 
which they are gradually attenuated ; they are six lines and a half 
wide at the broadest part near the summit, are quite glabrous, 
marked with about five pairs of nervures, which are remarkably — 
flexuose : the peduncles are one inch and a quarter, to one inch 
and a half long, very slender, but thickening towards the apex, - 
and quite glabrous; the calyx is small, campanular, two lines 
long, membranaceous, with five prominent nerves, and five short 
rounded teeth, marked on the edge with a marginal nerve; the 
corolla is one inch and a half long, contracted for about three 
lines at the base, and thence slightly infundibuliform, spreading 
into a short campanular mouth tomentose outside, with a pent- 
angular ciliate border, the angles being acute, and exhibiting in. 
the plicature of the sinus, a prominent, glabrous, rounded tooth ; 
the filaments arising from the upper part of the contraction of the 3 7
